Welcome back for another edition of the Sonic Hacking Contest!

As new developments occur in our scenes, we've got to keep ourselves up with them. Here's what's new:
- We're accepting mods of Sonic Advance 2 based on the decompilation, provided that they are built to run on a GBA. Unfortunately, we can not currently accept builds for other platforms due to security concerns;
- We're accepting entries based on Unleashed Recompiled;
- Due to long standing popular demand, we're accepting entries based on Sonic 1 Forever and Sonic 2 Absolute.
Please take a moment to read the updated rules, to make sure you won't find yourself in trouble later down the line.
There have been updates to the rules system, with select rules now only finding application for a specific category.
Not much else changed: the trophy list is the same, minus one trophy, it being the one awarding the best Team Entries (which half the time coincided with the Contest winners).
With that laid out, we look forward to seeing your entries, so as usual GET READY... SET... PROCRASTINATE!
